Poundal (pdl)

The poundal (pdl) is a unit of force in the foot-pound-second (FPS) system of measurement. It is defined as the force required to accelerate a one-pound mass by one foot per second squared. In other words,

1 poundal = 1 lb × 1 ft/s².

The poundal is much smaller than the more commonly used pound-force (lbf). It’s mainly used in some engineering contexts and classical mechanics problems where the FPS system is preferred. However, it is less common than the SI unit of force, the newton.

Conversion:

1 poundal ≈ 0.13825 newtons.

Grain [gr]

The grain (gr) is one of the oldest units of mass, traditionally used in various weight systems including troy, apothecary, and avoirdupois.

One grain is defined as exactly 64.79891 milligrams (0.0648 grams). It was originally based on the weight of a single grain of barley or wheat.

Grains are still commonly used today to measure small quantities such as the weight of bullets, arrows, and some pharmaceuticals.
